The Ulti-BoomPro-FB (Ultimate Support) is a fixed-length professional microphone boom arm designed for studio and live sound use.

Here’s a clear breakdown:

What it is

• A fixed boom arm (not a full stand—just the boom extension)
• Part of the Ultimate Support Ulti-Boom Pro series
• Designed to attach to standard mic stands (5/8"-27 threading)

Key features

• Fixed length ~34.75 in (883 mm)
• Ball-joint “Z-knob” adjustment system for angle, pan, and rotation control
• StableLock lever (keeps boom position locked without slipping)
• Die-cast counterweight (~0.65 lb / 0.3 kg) for stability
• Durable aluminum construction with anti-corrosion finish

What it’s used for

• Overhead drum miking
• Vocal mic positioning in studios
• Broadcast / podcast setups
• Stage mic placement where precision positioning matters

Simple way to understand it
Think of it as a high-end adjustable boom arm attachment that turns a normal mic stand into a much more precise, stable positioning system for microphones.
